Ökologieinstitut MAPE report (text only) - Uranium

It must be emphasized that uranium ore mining and processing has not only radiological hazards. There is also a potential impact due to "conventional" chemical pollutants like sulphuric acid and heavy metals which take part in or are a byproduct of uranium processing. Furthermore, other types of negative impact have to be considered as well.

Uranium processing - Canadian Nuclear Association

After mining, uranium ore is transported to a nearby mill for processing. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks, to separate the uranium from other minerals in the rock.

Uranium mining in Colorado - Wikipedia

Uranium mining in Colorado, United States, goes back to 1872, when pitchblende ore was taken from gold mines near Central City, Colorado.The Colorado uranium industry has seen booms and busts, but continues to this day. Not counting byproduct uranium from phosphate, Colorado is considered to have the third largest uranium reserves of any US state, behind Wyoming and New Mexico.
